Manage a Fief
When you occupy an enemy city, you can take it as a Fief.
Select a Policy and apply on the Fief.
You can collect the yield after the Policy completes.
Please note that Olympia will provide 150% yield.
If the Fief got occupied by others, your unclaimed yield will be lost.
The plunder, however, will get 50% of the yield.
